Materialize AutoComplete

To use Materialize autocomplete dropdown, You have to add following Html and js.

<div class="row">
     <div class="input-field col s12">
         <i class="material-icons prefix">textsms</i> // for prefix icon
         <input type="text" id="autocomplete-input" class="autocomplete"> // input feild id and class required
         <label for="autocomplete-input">Autocomplete</label> // label for input feild
     </div>
  </div>

document.addEventListener('DOMContentLoaded', function() {
    var elem = document.querySelectorAll('.autocomplete');
    var instance = M.Autocomplete.init(elems, options);
 });

We wrap our code inside DOM content eventlistener, So that it will run after document loading completed. 

Jquey

$(document).ready(function(){
    $('input.autocomplete').autocomplete({
      data: {
        "Apple": null,
        "Microsoft": null,
        "Google": 'https://placehold.it/250x250'
      },
    });
  });
